Source Codes in MATLAB 2019b. Want to migrate in 2024a. Is there any possibility of change in source codes when I migrate from 2019b to 2024a?

I have written all source codes and developed function blocks in MATLAB 2019b. I want to migrate it to 2024a version. Does the migration affect any of the data in source codes and the function blocks?

Also, scripts are developed in MATLAB 2019b to generate DLL and XML files. Now, when we do the migration, does it affect this scripts generating the DLL and XML files?

Pipelines are also developed in Azure DevOps for pushing the source codes and function blocks, scripts generating DLL, XML. When the migration is done, does it affect the pipelines?

We need to know also if the migration can be done without any changes in the source codes or function blocks developed in 2019b. Kindy guide and provide explanation on how to do that?

R2019a introduced Projects. Chances are that you did not use them in R2019b.

R2020a introduced some notable changes in Projects.

By the R2024a timeframe, Projects had become emphasized, and are now the major organization for deployment.

In principle there should not be any issue, but there could be some functions or uses that have been deprecated in newer matlab versions. Eg one I have encountered is `fopen('all')` throwing an error saying to use `openedFiles` instead. But this is the first time I have had such a problem with older code running in newer versions, so my prior is that things just work with newer versions. It is impossible to say much more though without knowing your code.
